The correct answer is:
The range is [0, 5].
Explanation:
The range of a function is the set of output values. This is the set of y-values of the function.
From the graph, we can see that the lowest y-value on the graph is 0, and the largest is 5. There are points at both locations; for this reason, we include them in our set and write our range as [0, 5].
